BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 257,460, dated May 9, 1882.

Application filed Octobcrtt, 188i. (Yo model.) i I To all zrhom it may concern Beitknown that I, H. G. BARKER, a citizen of the United States of America, residing at Scdalia, in the county of Pettis and State of Missouri, have invented certain new and useful Improvements in Brick-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification,and in wl1ich- Fignrel is a side elevation of my invention. Fig. 2 is an opposite side elevation with the die in its lower position. Fig. 3 is adetailed section through the press or molds.

Thisinvention relates to improvements in brick-machines, having for its o ject to effect the expeditious molding and proper shaping of the intended bricks; and it consists of the combination and arrangement of parts substantially as hereinafter more fully set forth.

In carrying out my invention I employ a frame, A, constructed, by preference, after the form ofthe ordinary pile-driver frame. Arranged parallel with the perpendicular uprights of said frame and bolted in position are the rods B, upon which the weight 0 and the die 0 are adapted to travel. The weight (J is provided with friction-rolls, which are interposed between it and the rods or guides B, is connected to the rope or cable I), which passes over a pulley, l), at the top of the frame A, and thence down to and around a segment, 0, upon a cog-wheel, E, and is beveled at its lower corners and provided just above its bev' eled corners with recesses or notches to permit it to engage with and be connected to the die (3, having the spring-catchesf, which enter the notches or recesses in the weight. The spring-catchesf have their upper ends beveled and so arranged as to be intercepted by pro- 5 jections g upon the bars or bows F, fastened at a suitably elevated point upon the sides of the uprights of the frame A, to effect the tripping or detaching of the die from the weight, to allow the die to enter the molds free of the preponderant weight of O, and thus avoid the exerting of too-great or a crushing force upon the contents of the molds and the mold bot- .toms or plungersbelow. The die G", which is adapted to suitably shape the clay into brick form, has eyes on its sides to receive the guiderods B, and a cushion of wood upon its upper end to break the concussion of the falling weight. To also overcome concussion the rods B are provided at their upper and lower ends with springs 71,

G is the clay-hopper, directly beneath which are located the mold-chambers 2', with a space between said hopper and the chambers or molds sufficient to allow the contents of the molds to be removed when lifted out of the molds.

H is apitman, which isprovidcd at its point ol'conncction with the shaft of the wheel E with a slot, to allow it to have the requisite intermittent motion for lifting the plungers or bottoms i of the molds flush with the upper edges of the latter, to lift out the contents of clay in brick form after the die 0' has been elevated. The slot of the pitman H consists of a bow, H, which receives a headed crankpin, H'Zon the shaft of the wheel E, and which has its armsscrew-threaded, and fitted thereon is a plate, H, to which the pitman is connect ed, while upon each side ofthe plate are nuts H The purpose of the foregoing is to effect the adjustment of the stroke of the pitman, and thus accordingly affect the movement of the moldplungers. The other end of the pitman H is connected by a crank,j, to a shaft,j, carry.- ing cams is, acting upon the-plungers or bottoms i of the molds, having the effect to elevate and depress the bottom or plunger '27. This arises from the fact that one arm, 7:, projects under a bar, '01, of the plunger or bottom i, and a second one above the said bar, which, it will be seen, act alternately upwardly and downwardly thereon as the shaftj is reciprocated by the pitman H.

1. is a second pitman, articulated to a plunger, 1, arranged to force the contents of the molds, when elevated out of the latter by the aforesaid mechanism, from under the hopper and out upon the table, or directly upon an off-bearing apron. The pitman I is connected to the shaft of the wheel E so as to have a sliding motion thereon. The wheel E has two spaced-apart cams, it, one facing in an on posite direction to the other, and thus adapted, as the wheel E revolves, to impart to the pitman I, each of two friction-rolls, 1' i upon which it strikes, firsta forward motion to cause it to push the plunger 1 forward, and then a backward motion to withdraw the plunger from under thehopperand out of the way of the descending die and weight. The pitman I is permitted to slide upon the shaft of the wheel E by being forked or bifurcated at that end. The plunger 1 moves upon rolls and over the die or mold chambers.

The wheel E is provided at one terminus of the segment 0 with a trip, J, which is adapted to slip the rope D off the segment at the proper moment, and thuspermit the weight and attached die to fall and force the clay into the mold-chambers, while not interfering with the continuous rotary motion ofthc wheel E. The trip J is capable ofadjnstment to permit it to be set more or less forward or backward to effect the tripping of the weight and attached die at difi'erent points of elevation, as may be desired. Power is applied to the wheel E through the shaft K, which is provided with a pinion, m, and may be connected to any suitable motor.

Having thus fully described my invention, I claim and desire to secure by Letters Patent- 1. The combination, with the weight O,having notches, and the intercepting latches or bars F, fixed to the uprights A, of the die 0, having the spring-catches f, substantially as and for the purpose set forth.

2. In a brick-machine, the combination, with the wheel-shaft E and the crank-shaftj, carrying the cams Ir, acting upon the mold-chamber plungers t" and the cranksj,ot' the pitman H, having a slot at its point of connection with said shaft, substantially as and for the purpose set forth.

3. In abrick-machine, the combination, with the plunger I and pitinan l, sliding upon the shaft of the wheel E, of the wheel E, having the oppositely-facing cams l l, substantially as and for the purpose set forth.

In testimony whereofI affix my signature in presence of two witnesses.
